With this box of Opaque Colours, you have chosen a product offering the Artist's quality you have come to expect from Stockmar. The artistically shaped box and classic metal design, contains 12 colour tabs. Each square can easily be taken out for quick replacements. The Stockmar mixing palette is not attached to the box, so you can put it down wherever is most convenient for your work - and of course it will be easier to clean than a painting box lid that is being used as a palette. In addition, your Stockmar box of Opaque colours contains a tube of Opaque white and a top quality Cat's Tongue Brush that holds its shape, made of Ponex synthetic hair and produced for Stockmar by the tradition-conscious German brush manufacturer Zahn. Like all of our Stockmar paints and colours, we have relied on Goethe's colour circle, but in an extended version. The three basic or primary colours form a triangle; between them are the secondary colours, formed by mixing the adjacent primaries - green from yellow and blue, orange from yellow and red, and violet from red and blue. The colours opposite to one another are complementary colours in which forms the widest possible contrast. If we now mix the primary with the secondary colours, we arrive at an extension of the colour circle. For example, we can mix red and violet to make red-violet, or yellow and orange to make yellow-orange. In order to enhance the range of colours, and to obtain a variety from mixing them, the Stockmar box of Opaque colours includes two tones of each basic colour: Lemon Yellow, Golden Yellow, Carmine Red, Vermilion, Ultramarine, and Prussian Blue. The Stockmar colours are delicately balanced with one another, and when mixed will yield harmonious shades of colours. Stockmar Opaque colours are suitable for various different painting techniques; classic opaque painting (over painting), classic watercolour painting, lazure painting or techniques based on a mixture of approaches.
